  • Inspecting a Word mail merge data source programmatically

    - by Guy Marom
    I want to iterate over all rows of a MS-Word mail merge data source and extract the relevant data into an XML. I'm currently using this code: Imports Microsoft.Office.Interop Do objXW.WriteStartElement("Recipient") Dim objDataFields As Word.MailMergeDataFields = DataSource.DataFields For Each FieldIndex As Integer In mdictMergeFields.Keys strValue = objDataFields.Item(FieldIndex).Value If Not String.IsNullOrEmpty(strValue) Then strName = mdictMergeFields(FieldIndex) objXW.WriteElementString(strName, strValue) End If Next objXW.WriteEndElement() If DataSource.ActiveRecord = LastRecord Then Exit Do Else DataSource.ActiveRecord = Word.WdMailMergeActiveRecord.wdNextDataSourceRecord End If Loop And it turns out to be a little sluggish (About 1 second for each row). Is there any way to do it faster? My fantasy is finding a function like MailMergeDataSource.ToDatatable and then inspecting the datatable.

  • Quick way to do data lookup in PHP

    - by Ghostrider
    I have a data table with 600,000 records that is around 25 megabytes large. It is indexed by a 4 byte key. Is there a way to find a row in such dataset quickly with PHP without resorting to MySQL? The website in question is mostly static with minor PHP code and no database dependencies and therefore fast. I would like to add this data without having to use MySQL if possible. In C++ I would memory map the file and do a binary search in it. Is there a way to do something similar in PHP?

  • How to properly reserve identity values for usage in a database?

    - by esac
    We have some code in which we need to maintain our own identity (PK) column in SQL. We have a table in which we bulk insert data, but we add data to related tables before the bulk insert is done, thus we can not use an IDENTITY column and find out the value up front. The current code is selecting the MAX value of the field and incrementing it by 1. Although there is a highly unlikely chance that two instances of our application will be running at the same time, it is still not thread-safe (not to mention that it goes to the database everytime). I am using the ADO.net entity model. How would I go about 'reserving' a range of id's to use, and when that range runs out, grab a new block to use, and guarantee that the same range will not be used.

What is the best way to search an element from an array in shortest time. Size of the array could be large enough, and any elements could be stored in the array(i.e. no range). Thanks.

  • Splitting data from MySQL using PHP & Javascript works in IE but not in FF

    - by MTSzabo
    I have the following JavaScript function on a page: function setFields(){ var menu = document.getElementById('EditLocation'); var itemDataArray = menu[menu.selectedIndex].value.split('|'); form.LocationShortName.value = itemDataArray[0]; form.LocationLongName.value = itemDataArray[1]; form.Phone.value = itemDataArray[2]; form.Address1.value = itemDataArray[3]; form.CityStateZip.value = itemDataArray[4]; form.MapLink.value = itemDataArray[5]; } Down on the Form, I have the following: <select class="input2" name="EditLocation" id="EditLocation" onchange = "setFields();"> <option value="-Add New-"<?php if($editlocation=='-Add New-'){echo(' selected="selected"');} ?>>-Add New-</option> <?php require_once('connection.php'); $connection = mysql_connect($hostname,$username,$password) or die (mysql_errno().": ".mysql_error()."<BR />"); mysql_select_db($database); $sql = "SELECT * FROM directions ORDER BY dirshortname"; $query = mysql_query($sql); while ($row = mysql_fetch_array($query)) { echo('<option value="'.stripslashes($row['dirshortname']).'|'.stripslashes($row['dirlongname']).'|'.stripslashes($row['dirphone']).'|'.stripslashes($row['dirstreet']).'|'.stripslashes($row['dircsz']).'|'.stripslashes($row['dirmaplink']).'"'); if ($editlocation==stripslashes($row['dirshortname'])) { echo(' selected="selected"'); } echo('>'.stripslashes($row['dirshortname']).'</option>'); } ?> In essence, the PHP is supposed to pack the data elements pulled from MySQL into the OPTION VALUE portion of the SELECT box. Once the user selects a record, the JavaScript pulls the packed data apart and populates the other data elements on the FORM. It all works wonderfully in IE, but in FF the fields do not populate with data. The form is somewhat long, but I'll include it anyway for the sake of completeness. <form action="admin-dirs.php" method="post" enctype="multipart/form-data" style="margin:0px; padding:0px " id="form"> <table width="587" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="60">&nbsp;</td> <td width="185">Select Location to Edit: </td> <td width="342"><select class="input2" name="EditLocation" id="EditLocation" onchange = "setFields();"> <option value="-Add New-"<?php if($editlocation=='-Add New-'){echo(' selected="selected"');} ?>>-Add New-</option> <?php require_once('connection.php'); $connection = mysql_connect($hostname,$username,$password) or die (mysql_errno().": ".mysql_error()."<BR />"); mysql_select_db($database); $sql = "SELECT * FROM directions ORDER BY dirshortname"; $query = mysql_query($sql); while ($row = mysql_fetch_array($query)) { echo('<option value="'.stripslashes($row['dirshortname']).'|'.stripslashes($row['dirlongname']).'|'.stripslashes($row['dirphone']).'|'.stripslashes($row['dirstreet']).'|'.stripslashes($row['dircsz']).'|'.stripslashes($row['dirmaplink']).'"'); if ($editlocation==stripslashes($row['dirshortname'])) { echo(' selected="selected"'); } echo('>'.stripslashes($row['dirshortname']).'</option>'); } ?> </select></td> </tr> <tr> <td width="60">&nbsp;</td> <td colspan="2"><span class="main" style=" padding-left:12px; padding-right:12px; padding-top:6px"><br /> (Note: Leaving the Long Name blank will duplicate the Short Name.)</span></td> </tr> <?php if(!$errlocationshortname=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errlocationshortname.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Location Short Name: <span class="red_star">*</span> </td> <td><input name="LocationShortName" id="LocationShortName" type="text" class="input2<?php if(!$errlocationshortname==''){echo('r');} ?>" value="<?php echo($locationshortname); ?>" maxlength="50"></td> </tr> <?php if(!$errlocationlongname=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errlocationlongname.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Location Long Name: <span class="red_star">*</span> </td> <td><input name="LocationLongName" id="LocationLongName" type="text" class="input2<?php if(!$errlocationlongname==''){echo('r');} ?>" value="<?php echo($locationlongname); ?>" maxlength="50"></td> </tr> <?php if(!$erraddress=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$erraddress.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Street Address: <span class="red_star">*</span> </td> <td><input name="Address1" id="Address1" type="text" class="input2<?php if(!$erraddress==''){echo('r');} ?>" value="<?php echo($address); ?>"></td> </tr> <?php if(!$errcsz=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errcsz.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>City, State, Zip: <span class="red_star">*</span> </td> <td><input name="CityStateZip" id="CityStateZip" type="text" class="input2<?php if(!$errcsz==''){echo('r');} ?>" value="<?php echo($csz); ?>"></td> </tr> <?php if(!$errphone=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errphone.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Location Phone Number: <span class="red_star">*</span> </td> <td><input name="Phone" id="Phone" type="text" class="input2<?php if(!$errphone==''){echo('r');} ?>" value="<?php echo($phone); ?>" maxlength="20"></td> </tr> <?php if(!$errmaplink=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errmaplink.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Paste Link to Map: <span class="red_star">*</span> </td> <td><input name="MapLink" id="MapLink" type="text" class="input2<?php if(!$errmaplink==''){echo('r');} ?>" value="<?php echo($maplink); ?>" maxlength="125"></td> </tr> <tr> <td>&nbsp;</td> <td>&nbsp;</td> <td><div align="right" style="padding-right:25px"> <input type="hidden" id="action" name="action" value="submitform" /> <input type="submit" id="savenew" name="savenew" value="Save & New" /> <input type="submit" id="submit" name="submit" value="Save & Close" /> <?php if(!isset($_POST['action'])) {?> <input type="reset" id="reset" name="reset" value="Reset" /> <?php } ?> </div></td> </tr><tr> <td>&nbsp;</td> <td>&nbsp;</td> <td class="main_d"><div align="right" style="padding-right:25px">Your IP Address is Logged as: <?php echo($ip); ?></div></td> </tr> </table> </form>

  • Panel data with binary dependent variable in R

    - by Abiel
    Is it possible to do regressions in R using a panel data set with a binary dependent variable? I am familiar with using glm for logit and probit and plm for panel data, but am not sure how to combine the two. Are there any existing code examples? Thank you. EDIT It would also be helpful if I could figure out how to extract the matrix that plm() is using when it does a regression. For instance, you could use plm to do fixed effects, or you could create a matrix with the appropriate dummy variables and then run that through glm(). In a case like this, however, it is annoying to generate the dummies yourself and it would be easier to have plm do it for you. Abiel

  • Conventional Approaches for Passing Data to Back-End?

    - by Calvin
    Hi guys, I'm fairly new to web development, so please pardon the painfully newbie question that's about to follow. My computer science class group and I are developing a web application for class, which is built in Python (under Django) and uses jQuery on the front end. It's primarily an AJAX-ified application, and passing data from the backend to the front end is done through AJAX calls to specific URLs which return JSON. This is probably a stupid question, but what's the conventional approach for passing data in the opposite direction? We don't want to reload the page or anything, so is it an AJAX pass going the other way or something? Thanks in advance for your help!

  • HTML, PHP No data in drop down box

    - by Makinitez21
    Hey, I am trying to figure out why a website's drop down box will not show any options. The data file for this drop down box comes from a microsoft access .mde file. The file is present and after the last update was working fine. Some changes happened to the site, i.e. text got added along with some photos. Im not saying this was when the drop down box went bad, but when it was discovered these were the only changes made. The data file seems fine as it is worked with everyday. Can anyone point me in the right direction as to where to begin looking for the bug? For a better idea of what I am talking about, check out the Site http://yogaalliance.org/teacher_search.cfm and try selecting a country. Thank you in advance

  • Find the min max and average of one column of data in python

  • Java: BufferedImage from raw BMP file format data

    - by Victor
    Hello there. I've got BMP file's raw pixels table in byte[], it's structure is: (b g r) (b g r) ... (b g r) padding ... (b g r) (b g r) ... (b g r) padding Where r, g, b are byte each, padding is to round row length up to a multiple of 4 bytes. So, how can I create new BufferedImage from this raw data without copying, just using this raw data? I took a look at creating BufferedImage from DataBuffer, but I just didn't get it. Unfortunately ImageIO is not allowed in my situation.

  • Extracting data points from a matrix and saving them in different matrixes in MATLAB

    - by Hossein
    Hi, I have a 2D Matrix consisting of some coordinates as below(example): Data(X,Y): 45.987543423,5.35000964 52.987544223,5,98765234 Also I have an array consisting of some integers =0 , for example: Cluster(M) 2,0,3,1 each of these numbers in this array corresponds with a row of my 2D Matrix above.For example, it says that row one(coordinate) in the Data Matirx belongs to the cluster 2,second row belongs to cluster 0 and so on. Now I want to have each of the datapoint of each cluster in a separate matrix, for example I want to save datapoints belonging to cluster 1 in a separate matrix, cluster 2 in a separate matrix and so on,.... I can do them manually, but the problem is this has to be an automatic extraction. which means that the number of clusters(range of the numbers in the cluster array varies in each run) so I have to have a general algorithm that does this extraction for me. Can someone help me please? thanks

  • Problems using jQuery $.ajax to pass data

    - by iboeno
    I'm using ASP.NET and attempting to call a method with a signature of [WebMethod] public static string GetInfo(string id){...} using the following javascript: var elementValue = $("#element").attr('id'); var d = "{id : " + elementValue + "}"; $.ajax({ type: "POST", url: "../WebPage.aspx/GetInfo", data: d, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { //do this } }); And this is not working. If instead I set elementValue = 2; it works fine. If I try to hardcode in a string value for testing purposes e.g. elementValue = "nameToLookUp"; It fails. Why is this happening, and how do I resolve it? On a side not, why is type: required to be POST instead of a GET? In the end I just want to pass a string value I want to look up in a DB and retrieving some json data.

  • Fault exception trashes a register causing a crash in [NSInvocation invoke]

    - by Mike Weller
    I have an NSOperation which fetches some objects from a core data persistent store and sums up a few totals. Sometimes an object is deleted while the operation in in progress, so a core data fault exception occurs. I try/catch the exception while summing to ignore it because I just want to skip objects that cannot be faulted in. However, when one of these fault exceptions occurs (and I swallow it) there is a crash after the invocation returns in [NSInvocation invoke]. It's a bad memory access when dereferencing the value in r10 which according to GDB on a successful run points to one of these: (gdb) x 0x38388348 0x38388348 <OBJC_IVAR_$_NSInvocation._retdata>: 0x00000008 If a fault exception occured a value of 0x02 is in the register which causes the crash. A quick google search tells me that r10 should be saved by the callee, meaning it is not being restored by whatever code is changing it when this exception occurs. Can anybody explain this? I'm not an expert when it comes to these kinds of low-level details

  • Transferring data to (Windows) Mobile Devices

    - by Ritu
    I created an app for Windows Mobile 6.5 and am fairly happy with it. However, if anyone else need to use this app, they will have to transfer an initial file (txt or csv) to the device. For a developer this isn't a problem but is this too much to ask of an end user? Granted, they will want to move (sync) data back to their desktop after the device's data have been updated. So how do other apps solve this problem? Do I need to provide some kind of syncing software?

I'm assuming it has to do with the .innerHTML call. Any insight would be deeply appreciated.

  • Getting camera preview data without using a preview callback

    - by velocipedestrian
    I have an app that does some processing to camera preview frames before displaying them to the user. I'm currently using preview callbacks to access the image data, but the problem I have is that the onPreviewFrame() function stops getting called if you start recording video using a MediaRecorder, and I want the processing to continue when video is being recorded. I've tried doing the following: public static Bitmap convertViewToBitmap(View view) { Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),view.getHeight(), Bitmap.Config.ARGB_8888); view.draw(new Canvas(bitmap)); return bitmap; } to convert the preview surface to a bitmap, but when I pass the preview SurfaceView to the function it returns an all-black bitmap (it works when I test it on normal views though). Is there any other way I can access the image data if preview callbacks are not available?
